My name is Debby Coffey, I was born in Milwaukee, Wisconsin and moved to Grass Valley, California when I was 6 years old. I graduated from Nevada Union High School. After graduation I attended Sac City College and Sierra College. After starting a family I worked in the electronic industry for Grass Valley Group and Eigen Video. Having 3 small children I chose to work in the dental industry. I worked for Dr. Wayne Hood and Dr. Craig Zelenka in which turned out to be a life long career. After Dr. Hood and Dr. Zelenka retired and sold the practice to Dr. Dana Gawley and Dr. Jeff Gawley I was lucky to continue in the practice as office manager. I now have the pleasure to be working for Dr. Joseph Miller. It is with great enthusiasm to work in my 3rd transition in this practice with all of our wonderful staff and great patients.
